Chevrolet Aveo, 2011

Chevrolet Aveo, 2011

The Chevrolet Aveo has been engineered to make everyday driving in a small car a more dynamic and enjoyable experience, while delivering practical, hands-on solutions and value. In order to ensure responsive handling, engineers developed an all-new chassis for the Aveo that is among the most rigid in its segment.
Featuring a sporty exterior that speaks Chevrolet's global design language, the all-new Chevrolet Aveo appeals to the young and the young-at-heart. This holds true for both body styles, but especially for the five-door hatchback, with its aggressive, flowing body lines. Meanwhile, the all-new four-door version conveys a more mature, upscale feel. The notchback is aimed at young families in particular.

A road-gripping ride
The new Chevrolet Aveo's sporty driving experience is a key feature that contributes to the car's appeal. It consists of an exceptionally rigid body-frame-integral structure, with the upper body and the frame engineered as a single unit, ensuring a more mass-efficient and stiffer structure. Advanced steels used on the new Aveo have considerably greater tensile strength, which improves passenger safety.

Two distinctive body styles
The new Chevrolet Aveo's external styling will bring a fresh breath of youth and sportiness to the segment. At the front end, the Aveo's large, dual-port grille with the centrally positioned bowtie immediately identify it as a Chevrolet.

A key signature element distinguishing the Chevrolet Aveo is its exposed, motorcycle-inspired headlamps, which are devoid of any lens cover. They are housed in dual tubes, with high-gloss black bezels and chrome rings. Pronounced wheel arch forms, the 114 mm offset between the roof-rails and short overhangs underscore the hatchback's planted, assertive posture.

As is the case in the Chevrolet Spark, the hatchback's rear door pull handles are positioned in the upper section of the door, creating a coupe-like appearance. The hatchback's taillamps have no lens cover and play harmoniously with the vehicle's front-end design. In contrast, the notchback's rear lamps are enveloped by a dual element lens, delivering a touch of chic to the sleek, aerodynamically refined sedan. The Chevrolet Aveo Sedan is 360 mm longer than the hatchback, which measures 4039 mm in length.
All wheels feature Chevrolet's five-spoke design and are available in the following sizes and styles: 15-inch steel and alloy, as well as 16-inch and 17-inch alloy.

Sporty sophistication inside
A high level of detail applied in the design of the Chevrolet Aveo's passenger cabin has resulted in a more upscale execution that is typically seen in higher-segment vehicles. On the same trim level, there is no difference in interior layout or styling between the hatchback and the sedan.
Efficient and fuel-saving powertrains
Fuel efficiency and enjoyable driving that creates a small environmental footprint were the main criteria guiding the design of the Chevrolet Aveo's engine lineup. The 1.6 liter gasoline engine (115 hp) gives the Aveo strong acceleration characteristics and an immediate feeling of performance during low-speed driving.

The petrol engine range also includes two 1.2 liter versions rated at 70 hp and 86 hp, respectively, a 1.4 liter unit (100 hp) and a 1.6 liter engine (115 hp). From this autumn, the new Chevrolet Aveo will also be offered with a 1.3 liter turbo-diesel engine - the first in a small Chevrolet in Europe - featuring common-rail fuel injection, start/stop technology and a variable-geometry turbocharger.

The 1.2 liter, 1.4 liter and 1.6 liter four-cylinder gasoline engines feature dual-overhead camshafts and variable valve timing. Their a cast-iron cylinder block is based on a hollow frame structure. The 1.2 liter and 1.4 liter engines feature a cast-iron bedplate that provides a stiffer structure, resulting in quieter and smoother engine performance. The 1.6 liter engine has a toothed timing belt that has a change interval of every 10 years or 160,000 kilometers.
Fuel consumption on a combined cycle is 5.1 liters/100 km for the 86 hp version of the 1.2 liter engine and 6.6 liters/100 km in the case of the 1.6 liter engine coupled with a manual transmission. The 1.2 liter Ecotec gasoline engine will emit 119 g of CO2 per km.

A tight chassis for confident road command
A wheelbase of 2525 mm, combined with wide, 1509 mm front and rear tracks, give the Chevrolet Aveo a firmly planted stance, which contribute to a balanced driving experience. The key enabler to its stability and confident road feel, however, is a very tight body-frame-integral (BFI) structure that ranks among the stiffest in the global small-car segment. Throughout the vehicle's structure, 10 percent more spot welds are used, while some of the steel selected to build the new Aveo exhibits tensile strengths of more than 1000 MPa or higher - twice as strong as the 340 to 550 MPa seen in the previous generation.

The chassis' main underbody rails run continuously from front to rear, providing great strength. A long, six-mount engine cradle contributes to lower noise levels, and smoother ride and handling dynamics. Specifically tuned engine mounts - including a hydraulic mount - are tailored to the engine's inherent torque axis, effectively disrupting the transmission of vibration and noise. This configuration also helps control the transfer of momentum, resulting in improved dynamic balance.
Sophisticated noise abatement
A stiffer structure also facilitates insulation of the powertrain and suppression of road and wind noise. Due to a drag co-efficient of 0.30, the Chevrolet Aveo has an excellent wind noise rating of 40.5 decibels at highway speed. Special damping mats, which are tailored to each specific powertrain package, act as an abatement to high-frequency noise transfer. Other measures aimed at achieving a quiet, pleasant cabin comfort level include the use of thicker glass for the windshield and windows, and the application of composite nylon baffles in various structural intrusions and of formed resin or felt blanket on the underside of the hood.

Small turn radius and advanced driving aid systems
An array of electronic systems assist the driver in maneuvering the Chevrolet Aveo through everyday traffic and more challenging driving situations. Turning diameter measures a tight 10.1 meters curb-to-curb, and less than three turns lock-to-lock, which are amongst the best in segment. In 1.2 and 1.3 liter diesel-equipped cars, a column-mounted electric power steering system (EPS) is available, which saves fuel when compared with an engine-driven power steering pump. In order to ensure precise steering action over the system's life, a wear compensator continually adjusts its interaction with the steering gear. This GM-engineered proprietary technology is an uncommon refinement in the segment.

Exterior Design
In line with its agile, athletic disposition, the all-new Aveo exhibits a purposeful, assertive appearance. From every angle, the redesigned Chevrolet Aveo Sedan and five-door models feature exterior forms that convey strength, stability and sportiness. A 114 mm offset between the roof rails and shoulder line, along with a track width of 1509 mm and pronounced wheel arches, ensure a confident, grounded posture. Progressive, raked body lines imply performance and suggest swift movement even when the car is stationary.

Chevrolet Aveo hatchback: coupe-like appearance with five-door functionality
While both the hatchback and the sedan speak a design language that appeals to the young and young-at-heart, their shapes differ in several important aspects. The five-door hatchback comes in a tight, two-box package, with aggressive diving feature lines and short front and rear overhangs. A sharply forward-swept shoulder line extends from the upper rear corner of the greenhouse to the front wheel arches. It runs in parallel to the lower body side scallop, accentuating the hatchback's forward-moving dynamic.
An upscale, sleek presence for the Chevrolet Aveo Sedan
The Chevrolet Aveo sedan shares the hatchback's purposeful, swift look, but features a number of characteristics that contribute to a more upscale, mature appearance. It is longer and wider (4399 mm x 1735 mm) than its predecessor, while its trunk has a cargo capacity of 502 liters - a 102 liter increase over the previous model.
Both the sedan and the hatchback sport a touchpad actuator on the liftgate, contributing to a smooth, refined opening action.
Precision work: minimized body panel gaps and weld joints
The exterior fit and finish on the new Chevrolet Aveo exemplify the attention to detail apparent throughout the vehicle. Door-to-door, door-to-fender, hood-to-fender, and lamp-to-fascia gaps, for example, are all 3.5 mm or less.

Interior Design
A small car with great performance and handling and a distinct, youthful appearance, the new Aveo also challenges competitors with a stylish, user-friendly passenger cabin. Its interior craftsmanship and refinements are designed to engage passengers with everything they see, touch or hear.
Cockpit emphasizes performance
Sportiness and sophistication characterize the Aveo's interior arrangement and details. The all-new Aveo features Chevrolet's signature dual-cockpit theme, originally a trademark of the Corvette, one of America's most iconic sports cars. Another key design element in the cabin is the wrap-around instrument panel. It flows from the dash into the doors.
Abundant, practical and discreet storage opportunities
Both the five-door hatch and four-door sedan models of the new Chevrolet Aveo offer generous cargo space. This includes an under-seat pullout drawer and a storage compartment beneath the cargo floor (hatchback). The luggage capacity of the notchback is 502 liters, while the five-door's luggage compartment holds 290 liters with the rear seat in the upright position. When the rear seat - a 60/40 design - is folded, the hatchback has a storage capacity of 653 liters. Front-seat travel is among the best in the segment: 189 mm forward, 54 mm rearward, 28 mm up and 37 mm down.

The mid-instrument panel features an upper glove-box with two compartments and outlets for USB and auxiliary devices, enabling discreet connectivity of iPods, smart phones, and other electronic devices. They can be operated through the steering-wheel controls or radio interfaces. A second, large glove-box features a lid that is damped for quiet operation.

Large storage pockets on both sides of the upper center stack in the instrument panel provide easy-to-reach storage areas for mobile phones, CDs and many other items. Three cupholders are located in the center console: Two for the front passengers and one for the rear-seat area.
Comfort and connectivity tailored to satisfy different needs
Tastes and comfort requirements may vary significantly and so does people's need to use modern communications and entertainment equipment. The designers of the Chevrolet Aveo have allowed for such variations. Seats are offered in three trim levels, color-coordinated according to the mid-instrument panel's color. Heated seats are optional on LT and LTZ models.

Two configurations of radios with four- or six-speakers and auxiliary device control are available. The audio system is capable of playing personal devices, such as the iPod through either the radio or steering wheel control. The uplevel radio offers USB/iPod as well as Bluetooth connectivity for wireless devices and also allows hands-free phone operation.

Engines & Transmissions
Today, a new car, and particularly a new entry to the small car segment, is expected to offer excellent fuel economy and a low carbon footprint, along with great performance and durability.
The Ecotec 1.2 and 1.4 liter gasoline engines make their debut in the new Aveo, while a new 1.3 liter turbo-diesel will be the first diesel in a Chevrolet's small cars in Europe. It debuts this autumn and features a high-performance common-rail fuel-injection system and advanced, electronically controlled variable geometry turbocharger with intercooler.
Fuel-efficient 1.2L and 1.4L gasoline engines
With the introduction of the newest entries of GM's family of small-displacement engines, the Chevrolet Aveo's powertrain benefits from a range of enhancements that display a strong performance and excellent expected longevity.

The engines' cylinder block is based on a hollow-frame structure, with a cast-iron bedplate. This stiff foundation ensures exceptional balance, smoothness and a quieter ride. The engineers also succeeded in raising the compression ratio to 10.5:1, thereby increasing fuel efficiency and improving emissions.

The 1.2 and the 1.4 liter gasoline engines feature dual-overhead camshafts and variable valve timing. The four-valve head design provides increased airflow as well as optimized cooling circuitry and inlet ports. Depending on the engines' speed and operating conditions, the valve timing can be tuned for optimum performance over a wide range of engine speeds while reducing fuel consumption.

The key features contributing to the 1.2 and 1.4 liter engines' durability and overall performance is improved oil circulation. This was achieved by integrating an oil/water heat exchanger that allows maximum interstage cooling and keeps pressure loss to a minimum. The cylinder block and lightweight aluminum cylinder head have dedicated bores to improve oil lubrication of the cam phasers. Piston-cooling oil jets also enhance oil lubrication, thereby increasing the engine's longevity.

The 1.2 liter gasoline engine, which is expected to be the highest-volume for the Aveo range, delivers 86 hp, and 115 Nm of torque at 4000 rpm. Performance figures for the 1.2 liter engine, when combined with the manual transmission, include a top speed of 183 km/h and a 0-100 km/h time of 13.6 seconds. Fuel consumption with the manual transmission on a combined cycle is 5.1 liters/100km, while emissions are 119 g of CO2/km. The 1.4 liter gasoline engine delivers 100 hp, and 130 Nm of torque at 4000 rpm.
1.6 liter gasoline engine delivers greater performance
The Chevrolet Aveo's 1.6 liter gasoline engine is rated at 115 hp. Not only does 1.6 liter engine's larger displacement provide more power, it also supports a robust peak torque of 155 Nm, which gives the Aveo strong acceleration characteristics and an immediate feeling of performance during low-speed driving.

The 1.2 and 1.4 liter engines, the 1.6 liter features a hollow-cast iron block and cylinder head made of aluminum. Despite its increased complexity, it weighs three percent less than previous generations of the same family of engines, while exhibiting greater stiffness and structural strength. In fact, the weight of the cylinder block was reduced by 20 percent compared to engine offerings from the previous generation.

The 1.6 liter engine is equipped with a 16-valve cylinder head with dual overhead camshafts. It also uses dual-continuously variable valve timing and shares the use of piston-cooling oil jets and oil circulation optimization features, similar to the 1.2 and 1.4 liter engines.

The 1.6 liter engine benefits from improved water circuit and thermal management systems. The cylinder head has been redesigned for significantly improved heat transfer and water distribution. Lower cooling water temperature adds to enhanced fuel efficiency thanks to less friction and heat loss through block and cylinder walls.
All-new transmission lineup includes six-speed automatic
A five-speed manual transmission is standard with the 1.2 and 1.4 liter gas engines, while a higher-capacity five-speed manual transmission is matched with the 1.6 liter. A GM Hydra-Matic six-speed automatic is optional on models with the 1.4 liter and the 1.6 liter engines, while a six-speed manual transmission will be offered exclusively with the 1.3 liter turbo-diesel later this year.

Safety
Ever increasing traffic volumes and limited amounts of space mean that even the most able, experienced and vigilant drivers may find themselves faced with the possibility of a collision in certain circumstances. Occupant safety is therefore an overriding objective for automotive engineers. The new Aveo is equipped with an array of safety features and sophisticated electronic control systems that are engineered to make it one of the safest vehicles in the small-car segment.

The backbone of Chevrolet Aveo's safety design is its exceptionally strong body structure provided by a body-frame-integral (BFI) structure. The BFI design is a single, welded unit consisting of full-length, high-strength frame rails and a safety cage. Welded tubular-section members are used to frame door openings and to support the roof while steel members reinforce the doors.
